Thats what I run in my bigger tank sumps and I don't get any algae anymore so I don't have any scrubbers lol
I have had many tanks setup on sponges mainly due to breeding purposes but they do a wonderful job and cost 10$ for a good one.
A sump for a 75 gallon is a little too much thats why I suggested a sponge filter. I have two sponge filters in my 200 gallon tank in addition to a 50 gallon sump. I mainly have it because of power outage reasons and the fact that when my pump is off when doing water changes the tank never loses filtration plus my small fish if they can't get any food munch of the bacteria or whatever is on that sponge filter to eat.
If you're dead set OP on getting a canister get a eheim or get a sun sun since its much cheaper. I can tell you this though all Canisters virtually do the same damn thing just depends on how much media can fit inside and how easy it is to disassemble.
Good Luck!
